You can start this quest after water level in the lake drops and you gain access to Old Crestwood. To learn how to do this, see the walkthrough for the Still Waters side quest. After you reach Old Crestwood, find the cottage with a friendly Wraith inside (M13,10). Talk to the wraith and take the quest to kill a Fury Demon in the Flooded Caves. You can now take the passage into the caves (M13,1f).

Defeat the Fury Demon

Fury Demonis staying in the Deepest Tier of the Flooded Caves (M14,2a). Remember not to attack with fire that the demon is resistant to (he is vulnerable to ice attacks, though) and deal with the weaker monsters as quickly as possible. You can now return to the surface and talk to the wraith again.
